Pachyphytum plant named ‘UB-PACHY-1801’

ABSTRACT

A new and distinct  Pachyphytum  cultivar named ‘UB-PACHY-1801’ is disclosed, characterized by foliage which is strong and strongly held on the plant, resisting both dropping and breaking off. Foliage has a distinct upward curve, giving the appearance of a full-bodied plant. Foliage is distinctly more lancet-like in shape. The new variety is a  Pachyphytum , useful as both an indoor ornamental plant, as well as an outdoor garden or container plant.

Latin name of the genus and species: Pachyphytum bracteosum.

Variety denomination: ‘UB-PACHY-1801’.

BACKGROUND OF THE INVENTION

The new cultivar, Pachyphytum ‘UB-PACHY-1801’, is the product of aplanned breeding program. The new variety originated from a crosspollination of the seed parent, an unnamed, unpatented Pachyphytumbracteosum with the pollen parent an unnamed, unpatented, Pachyphytumhookeri. The cross pollination was made during Spring of 2012 inKudelstaart, the Netherlands, at a commercial greenhouse. The newcultivar ‘UB-PACHY-1801’ was first selected by the inventor, Gert Ubink,during 2013.

Asexual reproduction of the new cultivar ‘UB-PACHY-1801’ was firstperformed in Kudelstaart, the Netherlands, by terminal vegetativecuttings in 2013. Pachyphytum ‘UB-PACHY-1801’ has since produced atleast 3 generations and has shown that the unique features of thiscultivar are stable and reproduced true to type. ‘UB-PACHY-1801’ wasfirst made available to the public Apr. 1, 2018, in the Netherlands.This sale was made directly by the inventor or one who obtained theclaimed invention directly or indirectly from the inventor. This saleand all public disclosures made between Apr. 1, 2018 and the filing ofthis application fall within the exception allowed under 102(b)(1).

SUMMARY OF THE INVENTION

The cultivar ‘UB-PACHY-1801’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘UB-PACHY-1801’. These characteristicsin combination distinguish ‘UB-PACHY-1801’ as a new and distinctPachyphytum cultivar:

-   1. Leaves are strong and strongly held, resistant to both dropping    and breaking off.-   2. Leaves curve upwards, giving plant more body.-   3. More lancet-like shaped leaves.

PARENTAL COMPARISON

Plants of the new cultivar ‘UB-PACHY-1801’ are similar to plants of theseed parent in most horticultural characteristics. However, plants ofthe new cultivar ‘UB-PACHY-1801’ differ in the following:

-   1. Leaves of new variety are much more firmly fixed to plant stem    than leaves of the seed parent.-   2. Plants of the new cultivar are wider than plants of the seed    parent.-   3. New variety has shorter internodes than the seed parent.

Plants of the new cultivar ‘UB-PACHY-1801’ are similar to the pollenparent in most horticultural characteristics. However, plants of the newcultivar ‘UB-PACHY-1801’ differ in the following:

-   1. The new variety's leaves are wider than leaves of the pollen    parent.-   2. The new variety's leaves are much more flat than leaves of pollen    parent.

COMMERCIAL COMPARISON

The new cultivar ‘UB-PACHY-1801’ can be compared to the unpatentedcommercial variety Pachyphytum ‘DRACO’. Plants of the new cultivar‘UB-PACHY-1801’ are similar to ‘DRACO’ in most horticulturalcharacteristics. However, plants of the new cultivar ‘UB-PACHY-1801’differ in the following:

-   1. ‘UB-PACHY-1801’ has a blue-green leaf color; ‘DRACO’ has a    slightly purple leaf color.-   2. ‘UB-PACHY-1801’ has more lancet-shaped leaves than ‘DRACO’.

The new cultivar ‘UB-PACHY-1801’ can be compared to the unpatentedcommercial variety Pachyphytum ‘Lila Cina’. Plants of the new cultivar‘UB-PACHY-1801’ are similar to ‘Lila Cina’ in most horticulturalcharacteristics. However, plants of the new cultivar ‘UB-PACHY-1801’differ in the following:

-   1. ‘UB-PACHY-1801’ has a blue-green leaf color; ‘Lila Cina’ has a    grey leaf color.-   2. ‘UB-PACHY-1801’ has more lancet-shaped leaves than ‘Lila Cina’.-   3. ‘UB-PACHY-1801’ has more upright-growing leaves; ‘Lila Cina’ has    more flat leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs in FIG. 1 and FIG. 2 illustrate in fullcolor typical plants of ‘UB-PACHY-1801’ grown in a greenhouse inKudelstaart, The Netherlands. The photographs were taken usingconventional techniques and equipment. The plant photographed is 12months old. While the colors in these photographs may display variancesof color as compared to the living cultivar, due to LRV (lightreflectance value), they are as accurate as possible using conventionalphotographic techniques. Colors in the photographs may appear to differslightly from the color values cited in the botanical description, whichaccurately describe the colors of the new Pachyphytum plant. Thefollowing photographs depict plants grown under two different naturallight conditions. Temperatures ranged from approximately 2° C. to 38° C.night and day. No artificial light, photoperiodic treatments or chemicaltreatments were given to the plants.
